Transform3D
|
||
===========
|
||
|
||
A 3×4 matrix representing a 3D transformation.

Description
|
||
-----------
|
||
|
||
The **Transform3D** built-in :ref:`Variant<class_Variant>` type is a 3×4 matrix representing a transformation in 3D space. It contains a :ref:`Basis<class_Basis>`, which on its own can represent rotation, scale, and shear. Additionally, combined with its own :ref:`origin<class_Transform3D_property_origin>`, the transform can also represent a translation.
|
||
|
||
For a general introduction, see the :doc:`Matrices and transforms <../tutorials/math/matrices_and_transforms>` tutorial.
|
||
|
||
\ **Note:** Godot uses a `right-handed coordinate system <https://en.wikipedia.org/wiki/Right-hand_rule>`__, which is a common standard. For directions, the convention for built-in types like :ref:`Camera3D<class_Camera3D>` is for -Z to point forward (+X is right, +Y is up, and +Z is back). Other objects may use different direction conventions. For more information, see the `3D asset direction conventions <../tutorials/assets_pipeline/importing_3d_scenes/model_export_considerations.html#d-asset-direction-conventions>`__ tutorial.
|
||
|
||
.. note::
|
||
|
||
There are notable differences when using this API with C#. See :ref:`doc_c_sharp_differences` for more information.

Constants

---------
|

.. _class_Transform3D_constant_IDENTITY:
|

|

.. rst-class:: classref-constant
|
||

||
**IDENTITY** = ``Transform3D(1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 0, 0)`` :ref:`🔗<class_Transform3D_constant_IDENTITY>`
|
||
|
||
The identity **Transform3D**. This is a transform with no translation, no rotation, and a scale of :ref:`Vector3.ONE<class_Vector3_constant_ONE>`. Its :ref:`basis<class_Transform3D_property_basis>` is equal to :ref:`Basis.IDENTITY<class_Basis_constant_IDENTITY>`. This also means that:
|
||
|
||
- Its :ref:`Basis.x<class_Basis_property_x>` points right (:ref:`Vector3.RIGHT<class_Vector3_constant_RIGHT>`);
|
||
|
||
- Its :ref:`Basis.y<class_Basis_property_y>` points up (:ref:`Vector3.UP<class_Vector3_constant_UP>`);
|
||
|
||
- Its :ref:`Basis.z<class_Basis_property_z>` points back (:ref:`Vector3.BACK<class_Vector3_constant_BACK>`).

||

var basis = transform.basis
|

If a :ref:`Vector3<class_Vector3>`, an :ref:`AABB<class_AABB>`, a :ref:`Plane<class_Plane>`, a :ref:`PackedVector3Array<class_PackedVector3Array>`, or another **Transform3D** is transformed (multiplied) by this constant, no transformation occurs.
|
||
|
||
\ **Note:** In GDScript, this constant is equivalent to creating a :ref:`Transform3D<class_Transform3D_constructor_Transform3D>` without any arguments. It can be used to make your code clearer, and for consistency with C#.

|
||
|
||
**Transform3D** with mirroring applied perpendicular to the YZ plane. Its :ref:`basis<class_Transform3D_property_basis>` is equal to :ref:`Basis.FLIP_X<class_Basis_constant_FLIP_X>`.

|
||
|
||
**Transform3D** with mirroring applied perpendicular to the XZ plane. Its :ref:`basis<class_Transform3D_property_basis>` is equal to :ref:`Basis.FLIP_Y<class_Basis_constant_FLIP_Y>`.

|
||
|
||
**Transform3D** with mirroring applied perpendicular to the XY plane. Its :ref:`basis<class_Transform3D_property_basis>` is equal to :ref:`Basis.FLIP_Z<class_Basis_constant_FLIP_Z>`.

|
||
|
||
The :ref:`Basis<class_Basis>` of this transform. It is composed by 3 axes (:ref:`Basis.x<class_Basis_property_x>`, :ref:`Basis.y<class_Basis_property_y>`, and :ref:`Basis.z<class_Basis_property_z>`). Together, these represent the transform's rotation, scale, and shear.

:ref:`Transform3D<class_Transform3D>` **Transform3D**\ (\ ) :ref:`🔗<class_Transform3D_constructor_Transform3D>`
|
||
|
||
Constructs a **Transform3D** identical to :ref:`IDENTITY<class_Transform3D_constant_IDENTITY>`.
|
||
|
||
\ **Note:** In C#, this constructs a **Transform3D** with its :ref:`origin<class_Transform3D_property_origin>` and the components of its :ref:`basis<class_Transform3D_property_basis>` set to :ref:`Vector3.ZERO<class_Vector3_constant_ZERO>`.

|

|
||
Constructs a **Transform3D** from a :ref:`Projection<class_Projection>`. Because **Transform3D** is a 3×4 matrix and :ref:`Projection<class_Projection>` is a 4×4 matrix, this operation trims the last row of the projection matrix (``from.x.w``, ``from.y.w``, ``from.z.w``, and ``from.w.w`` are not included in the new transform).

Constructs a **Transform3D** from four :ref:`Vector3<class_Vector3>` values (also called matrix columns).

The first three arguments are the :ref:`basis<class_Transform3D_property_basis>`'s axes (:ref:`Basis.x<class_Basis_property_x>`, :ref:`Basis.y<class_Basis_property_y>`, and :ref:`Basis.z<class_Basis_property_z>`).

.. _class_Transform3D_method_affine_inverse:

|

:ref:`Transform3D<class_Transform3D>` **affine_inverse**\ (\ ) |const| :ref:`🔗<class_Transform3D_method_affine_inverse>`
|
||
|
||
Returns the inverted version of this transform. Unlike :ref:`inverse()<class_Transform3D_method_inverse>`, this method works with almost any :ref:`basis<class_Transform3D_property_basis>`, including non-uniform ones, but is slower. See also :ref:`Basis.inverse()<class_Basis_method_inverse>`.
|
||
|
||
\ **Note:** For this method to return correctly, the transform's :ref:`basis<class_Transform3D_property_basis>` needs to have a determinant that is not exactly ``0.0`` (see :ref:`Basis.determinant()<class_Basis_method_determinant>`).

|
||
|
||
Returns the result of the linear interpolation between this transform and ``xform`` by the given ``weight``.
|
||
|
||
The ``weight`` should be between ``0.0`` and ``1.0`` (inclusive). Values outside this range are allowed and can be used to perform *extrapolation* instead.

\ **Note:** For this method to return correctly, the transform's :ref:`basis<class_Transform3D_property_basis>` needs to be *orthonormal* (see :ref:`orthonormalized()<class_Transform3D_method_orthonormalized>`). That means the basis should only represent a rotation. If it does not, use :ref:`affine_inverse()<class_Transform3D_method_affine_inverse>` instead.

|
||
|
||
Returns a copy of this transform rotated so that the forward axis (-Z) points towards the ``target`` position.
|
||
|
||
The up axis (+Y) points as close to the ``up`` vector as possible while staying perpendicular to the forward axis. The resulting transform is orthonormalized. The existing rotation, scale, and skew information from the original transform is discarded. The ``target`` and ``up`` vectors cannot be zero, cannot be parallel to each other, and are defined in global/parent space.
|
||
|
||
If ``use_model_front`` is ``true``, the +Z axis (asset front) is treated as forward (implies +X is left) and points toward the ``target`` position. By default, the -Z axis (camera forward) is treated as forward (implies +X is right).

Returns a copy of this transform with its :ref:`basis<class_Transform3D_property_basis>` orthonormalized. An orthonormal basis is both *orthogonal* (the axes are perpendicular to each other) and *normalized* (the axes have a length of ``1.0``), which also means it can only represent a rotation.

Returns a copy of this transform rotated around the given ``axis`` by the given ``angle`` (in radians).

The ``axis`` must be a normalized vector (see :ref:`Vector3.normalized()<class_Vector3_method_normalized>`). If ``angle`` is positive, the basis is rotated counter-clockwise around the axis.

This method is an optimized version of multiplying the given transform ``X`` with a corresponding rotation transform ``R`` from the left, i.e., ``R * X``.
